Know What HVAC Service You’re Paying For

You deserve simple pricing: no markups on parts, no surprise repair fees, and no confusion. Here’s what honest pricing looks like:

  • Clear pricing upfront
  • No markup on parts
  • No overtime charges
  • 2Y warranty on all repairs
  • 10Y warranty on all new installations

It’s just how an HVAC company should do business.

Boardman Homeowners Asked. We Answered.

Do you charge a service call fee for sending an HVAC pro to my home?

Yes. It’s a flat $85 to have one of our technicians come out and diagnose your issue. We don’t charge overtime, and we don’t charge a markup on parts. Yes, really. What we pay is what you pay.

What kind of guarantee comes with your HVAC services?

We are proud to stand by every job with a 2-year warranty on all HVAC repairs and a full 10-year warranty on all new heating and AC installations.

How soon can you be out to my house in Boardman?

We offer same-day HVAC service whenever possible—especially for urgent heating or air conditioning issues. Whether you need a quick repair or are looking into a full installation, we’ll work to get a technician to your home in Boardman as soon as we can.

How much do HVAC repairs usually cost?

At Gault, we keep repair pricing simple and fair. Most HVAC repairs fall into our lower pricing tiers—92% of customers pay under $200. You’ll get a clear quote before any work starts, and we never mark up parts or charge hidden fees. Just straightforward pricing and a 2-year warranty on all repairs.

How often should I schedule HVAC maintenance?

Twice annually is best, once in the spring for AC and once in the fall for heating. If that’s not doable, even one scheduled maintenance service at the start of the season can help your system last longer and run more efficiently.

What are the signs that my house needs a duct cleaning service?

Generally speaking, duct cleaning should be handled every 3 to 5 years. If you notice dust buildup around vents, musty smells, allergy-type symptoms, or uneven airflow, it’s probably time to give your ducts some attention.

How do I know if it’s time for an AC or heating replacement?

If your AC system’s age is over 15, needs frequent maintenance, or struggles to keep your home comfortable, a replacement might be a better option than opting for yet another fix. Our technicians can help you determine the best path forward.

What should I expect during an HVAC installation?

Once you’ve chosen a system, our team handles everything—removal of your old equipment, proper sizing, permits, installation, and clean-up. Most HVAC installations take about a day, and we’ll walk you through how everything works before we go.

What can I do to improve indoor air quality?

Keeping your ducts clean is a great start. We can also install and maintain purifiers, UV lights, humidifiers, and dehumidifiers.

I couldn’t be happier with Gault. There were no games played. Just a very fair priced, straight to the point estimate for new central a/c and furnace. Installed the following week. Everyone was great. Highly recommend!

They installed a new H/H furnace and A/C unit in my home and it has a noticeable difference already. The old unit was undersized and looked like some 8 year old installed it, the new equipment is first class. But now with properly sized ductwork the home is much more comfortable. You only get what you pay for.

We have our home and an apartment above our detached garage and have had both furnaces replaced in each. Great service. Great installations. Checkups were both great.  Would definitely recommend the company! All employees have been pleasant and helpful.

They did it all in one day and they were efficient. We were told one of the guys was new. There was a small leak in the system, but they came back the same day and fixed it. Their price was very competitive.

Gault does our gas furnace tune up every year. They’re friendly and easy to schedule service with and the technicians are always polite and helpful. Great company to deal with.
